String replacement is the wrong way to go about this.

Use the Context.Request.QueryString dictionary to get the value of BSCID.

if (!String.IsNullOrEmpty(Context.Request.QueryString["BSCID"]))
{
    var BSCID = Context.Request.QueryString["BSCID"];
}

What do you get if you examine `Context.Request.QueryString.ToString()`? – Ash Nov 23 '17 at 23:19
